Right now, it's still winter in Yellowstone, and these unsuspecting buffalo are following historic migratory routes in search of food at lower elevations where there is less snow.

When the buffalo venture near or beyond the park's boundary, they will continue to be rounded up and killed - unless we start a national outcry:

What makes this sacrifice so senseless is that it's all to protect 12 to 16 domestic cows and steers that graze near the park from the theoretical risk of a disease - brucellosis - that has never been transmitted from bison to cattle in a natural setting.

Yes, you read those numbers right: 1,000 wild bison slaughtered to protect a little more than a dozen cows outside the park that have most likely been vaccinated against the disease, or easily could be.
